Model best practices

Oh, I'm sorry, I was thinking you meant it like this

Code:

class A_Model extends CI_Model {

    public function __construct() {
        parent::__construct();
    }

    public function set_var1($var1) {
        $this['var1'] = $var1; // using $this as array
        return $this;
    }
    public function set_var2($var2) {
        $this['var2'] = $var2; // using $this as array
        return $this;
    }

    public function create() {
        foreach ($this as $var => $value)
            $this->db->set($var, $value);
        $this->db->insert('table');
        // Should really check if everything went OK, but hey…
    }

}
